Documentation in readme about requests id contradicts code

From the readme:
The actual method for generating request IDs doesn't matter as long as
they are even numbers (e.g. 0, 2, 4, ...) and aren't re-used by different
requests on the same connection (but note that some requests may involve
multiple messages). Server responses to a client request will use the
client-supplied request ID, but server-originated messages will have a
server-assigned ID which is odd (e.g. 1, 3, 5, ...). In effect, when the
low bit of the request ID is set, it indicates a server-initiated request.

I believe this is out of date -- the code seems to have server have even ids and client odd ones, the opposite of the README.

request.py also has a comment that still reflects the old usage, in RequestHandler.get_new_request_id().
